The pressure drop in a Venturi meter varies only with the fluid density, pipe approach velocity, and the diameter ratio of the meter. A model Venturi meter tested in water at 20 ?C shows a 5-kPa drop when the approach velocity is 4 m/s. A geometrically similar prototype meter is used to measure gasoline (? = 680 kg/m3) at 20 ?C and a flow rate of 9 m3/min. If the prototype pressure gage is most accurate at 15-kPa, what should the upstream pipe diameter be?
